接口設(shè)計(jì)方案

1、接口設(shè)計(jì)方案一、設(shè)計(jì)方案由甲方調(diào)用監(jiān)控模塊,控制監(jiān)控模塊的啟停、設(shè)置策略等，通過(guò)甲方調(diào)用監(jiān)控模塊DLL的接口將監(jiān)控策略告知監(jiān)控模塊，由監(jiān)控模塊監(jiān)控相關(guān)操作行為，并根據(jù)策略配置調(diào)用甲方提供的文件內(nèi)容檢查模塊，對(duì)相關(guān)文件進(jìn)行文件內(nèi)容篩查，來(lái)確定文件是否是涉密文件。同時(shí)通過(guò)甲方程序調(diào)用乙方監(jiān)控模塊DLL接口獲取監(jiān)控結(jié)果。甲方文件內(nèi)容檢查模塊甲方程序監(jiān)控監(jiān)控模塊DLL一、接口部分（監(jiān)控模塊DLL,乙方提供）*Function:InitDescription:初始化操作Input:無(wú)Output:無(wú)Return：true：成功，false：失敗Other:*1、bool Init();*Function

2、:SetRuleDescription:設(shè)置監(jiān)控規(guī)則Input:char* pRule：監(jiān)控規(guī)則，XML格式，見附1Output:無(wú)Return：true：成功，false：失敗Other:*2、bool SetRule(char* pRule);*Function:StartDescription:設(shè)置完規(guī)則，啟動(dòng)監(jiān)控規(guī)則生效Input:無(wú)Output:無(wú)Return：true：成功，false：失敗Other:*3、bool Start();*Function:WaitDataDescription:實(shí)時(shí)等待獲取監(jiān)控?cái)?shù)據(jù)可以是一條可以是多條。返回監(jiān)控結(jié)果見附2Input:無(wú)Output:i

3、nt &nCount返回總條數(shù)，char*&pData返回?cái)?shù)據(jù)。Return：-1.異常0.成功獲取數(shù)據(jù)1.結(jié)束 / 停止（其他地方調(diào)用Stop接口停止）Other:建議乙方內(nèi)部實(shí)現(xiàn)用信號(hào)、內(nèi)核事件等處理方式。*4、int WaitData(int &nCount, char*& pData);甲方調(diào)用偽代碼：ThreadFunc()/實(shí)時(shí)線程While(TRUE) char* pData = NULL; int nCount = 0; int nRet = WaitData(nCount,pData);/等待一條或多條數(shù)據(jù)時(shí)返回,沒(méi)有數(shù)據(jù)就等待。 switch

4、(nRet) -1.異常continue;0.成功獲取數(shù)據(jù) pData0、pData1、1.結(jié)束 / 停止（其他地方調(diào)用Stop停止） Return;FreeData(pData);*Function:FreeDataDescription:釋放數(shù)據(jù)內(nèi)存接口，對(duì)應(yīng)WaitData函數(shù)Input:int nCount 要釋放的元素?cái)?shù)量，char*要釋放的數(shù)據(jù)Output:無(wú)Return：無(wú)Other:*5、FreeData (int nCount ,char* pData);*Function:StopDescription:停止監(jiān)控，監(jiān)控規(guī)則失效Input:無(wú)Output:無(wú)Return：tr

5、ue：成功，false：失敗Other:*6、bool Stop();*Function:UnInitDescription:程序退出Input:無(wú)Output:無(wú)Return：true：成功，false：失敗Other:*7、UnInit();二、文件檢查模塊/*接口說(shuō)明*/創(chuàng)建文件檢查實(shí)例void (*PCreateFileCheckerObject)(IFileChecker *pObject);/釋放文件檢查實(shí)例void (*PReleaseFileCheckerObject)(IFileChecker *pObject);多規(guī)則多種關(guān)鍵字組合，則創(chuàng)建多個(gè)實(shí)例- IFileChecke

6、r-/初始化void Init(const char *pName, const char *pKeyWords);pName:實(shí)例名稱隨意。但多個(gè)實(shí)例并行時(shí)不能重復(fù);pKeyWords: 關(guān)鍵詞組。格式："機(jī)密;秘密;絕密;"/結(jié)束調(diào)用void UnInit();/獲取文件信息bool GetFileInfo(const char *pFilePath, TipsFileBlock *pTFB);pFilePath：文件路徑pTFB：返回?cái)?shù)據(jù)結(jié)構(gòu)/釋放文件信息void FreeFileInfo(TipsFileBlock * pTFB);pTFB：需要釋放的數(shù)據(jù)結(jié)構(gòu)/停止

7、當(dāng)前的文件檢查void StopCheck();*/-(.h)頭文件如下-#pragmaoncestructTipsFileBlockchar *pKeyWords;/關(guān)鍵字char *pSecretLevel;/密級(jí):秘密、機(jī)密、絕密中的一個(gè)char*pFileBlock;/片段;classIFileCheckerpublic:virtualvoidInit(constchar *pKeyWords) = 0;virtualboolGetFileInfo(constchar *pFilePath, TipsFileBlock *pTFB) = 0;virtualvoidFreeFileInf

8、o(TipsFileBlock * pTFB) = 0;virtualvoidUnInit() = 0;virtualvoidStopCheck() = 0;typedefvoid (*PCreateFileCheckerObject)(IFileChecker *pObject);typedefvoid (*PReleaseFileCheckerObject)(IFileChecker *pObject);/-頭文件 end-/示例/-獲取接口類-HMODULE hDll = LoadLibrary(_T("TipsFileChecker.dll");if (NULL =

9、hDll) return;PCreateFileCheckerObjectpCreateFileChecker = (PCreateFileCheckerObject)GetProcAddress(hDll,"CreateFileCheckerObject");PReleaseFileCheckerObjectpReleaseFileChecker = (PReleaseFileCheckerObject)GetProcAddress(hDll,"ReleaseFileCheckerObject");if (NULL = pCreateFileCheck

10、er | NULL = pReleaseFileChecker) return;IFileChecker* pFileChecker = NULL;pCreateFileChecker(&pFileChecker);/-初始化提供關(guān)鍵字-CStringAstrName = "FeiMi1"/多個(gè)實(shí)例名稱任意，但不同。例如：FeiMi2、FeiMi3、CStringAstrKeyWords = "秘密;機(jī)密;絕密; "pFileChecker->Init(strName,strKeyWords);/-文件命中片段提取-CStringAstrF

11、ilePath = "C:123.docx"TipsFileBlockfb;pFileChecker->GetFileInfo(strFilePath,&fb);/.pFileChecker->FreeFileInfo(&fb);/-結(jié)束釋放-pFileChecker->StopCheck();pFileChecker->UnInit();pReleaseFileChecker(&pFileChecker);FreeLibrary(hDll);三、附附1：規(guī)則XML：<TipsTCM><TipsTypeTyp
